Bacteria can break down hydrocarbons in the soil, but how quickly the compounds degrade depends on how rapidly they reach the bacteria. Fibrous networks of fungi and related organisms might be able to help, researchers have discovered. Threads in these networks, which transport nutrients through the organisms’ bodies, also transport oily contaminants (Environ. Sci. Technol., DOI: 10.1021/es300810b). The networks . . .
